But, if Siri were to someday work as quickly and accurately as
Google, here's where its answers would be coming from. Munster
assembled a list of who powers Siri and how it's changed from iOS
5 to iOS 6. As you can see, Apple Maps got a big boost, but Google is still
important.

Munster believes Siri still has a chance to become something real
for Apple. He thinks it needs to point people to more commerce
sites, and he thinks it could eventually integrate with Groupon or LivingSocial to offer users deals.
